WVE/VT R i To all whomz't mai) concern: Be it known that I, HENRY H. FINN, av

citizen of the United States, residing at Orono, in the county of Penobscot and State of Maine, have invented certain Improvements in Hydraulic Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on 1d the drawings indicating like parts in the several figures.

This invention relates to hydraulic apparatus, and more specifically to combined water motors and pumps.

The invention has for its chief object to devise an apparatus of this character in which the energy of a current of water can be utilized to ,raise automatically a part of the water to a point above the orlginal head.

It is a further object of the invention to devise an apparatus of the character 1nd1- cated which can be economically manufactured, in which Wear and deterioration shall be reduced to a minimum, and which will require but little attention while in use. The invention will be readily understood from the following description of one embodiment thereof, reference being made to the figure of the accompanying drawing which shows a central, longitudinal section of an apparatus constructed in accordance with the invention.

The apparatus shown comprises a 'caslng 2 which may be made of any convenient number of sections and is designed, when in use, to be set in a vertical position. This easing has a lateral intake opening 4 intermediate of its ends and two discharge pass 40 sages extending in substantially opposite directions; one, indicated at 6, extending downwardly and the other, indicated at 8, extending upwardly, from theintake opening. A diaphragm 10, projecting from the back of the easing into the intake, serves to direct the greater part of the water entering the intake opening into the lower discharge passage 6 and a smaller part into the upper passage '8.

The casing rests upon a skeleton'stool, or

frame 12, which has several legs of such a height and depth that the space between them is much greater than the cross sectional area of the discharge passage 6 so that abundant room is prov ded for the flow ameter. The casing above the PATENT OF CE j Specification of Letters Patent. t t Man 23 .1915;

of water out of the casing Theframework 12 also includes a central post 14 in the upper end of which is formed a step bearing 16 I for a shaft 18 that extends longitudinally through the'discharge passages 6 and 8, ad'- 'ditional. bearings being provided for this shaft in the diaphragm 10 and in the upper end of the casing at 20. For convenience in assembling, this shaft ma be made in two] sections connected as indlcated at 21 by a joint-located inside the bearing in the diaphragm.

Fast on the shaft 18 and positioned with in the lower discharge passage 6 is a water wheel 22 which may be of any suitable construction but, .in the form shown, consists of aplurality of blades extending spirally along the shaft 18 and wide enough to fit as snugly within the walls of the discharge passage. 6 as possible while providing the necessary clearance. Fast on the shaft 18 in the. passage 8 is a rotary pump which may be of any suitable t pe, but as shown,

consists of a plurality 0 blades 24 similar I to the blades 22, but preferably 'of a lesser pitch and, of course, of a much smaller diump 24 is turned at an angle to provide or the convenient attachment thereto of the pipe or conduit, by which the water leaving the pump is to be conducted away.

It will now be understood that, when'the casing is set in operative position, its intake end being connected to a penstock leading from .a suitable head of water, the in'flowing current of water will be divided by thediapump 24 in lifting the water.

It will'be understood, of course, that the dimensions of the casing and pump will be varied in accordance with the particular conditions under which the apparatus is to. be operated.

Having thus described my invention, what a lateral intake passage and two ischarge passages leading from said intake passage.

in substantially opposite directions, a diaphragm projecting from the back of the easing toward said intake passage and-serving to direct water entering the intake passage into the discharge passages, a rotary shaft extending longitudinally through both of said discharge passages and having a hear ing in said diaphragm, a water wheel having spiral blades mounted onsaid shaft in one of said discharge passages and a rotary pump having spiral blades of less pitch than the blades of said water wheel mounted on .the shaft in the other discharge passage.

2. In anapparatus of the character de scribed, the combination of a vertical casing having a lateral intake passage, a discharge passage leading downwardly fromsaid intake and a smaller discharge passage leading upwardly from said intake, a diaphragm extending from the back of the casing toward said intake and serving to direct the water entering the intake into said discharge passages, a stool mounted at the bottom of said. casing to support the casing, a

thrust bearing in said stool, a shaft extending longitudinally through said discharge passages and having its lower end supported in said thrustbearing, said shaft having bearings in said diaphragm and in the upper part of said casing, a water wheel having spiial blades mounted on said shaft in thefltiwer discharge passage and substantiallyfilliil'fg said passage, and a rotary pump
